BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention is related to a display panel and a method of driving the display panel, and especially related to a display panel having a favorable aperture ratio and a method of driving the display panel.

2. Description of Related Art

In recent years, with the progress of semiconductor industry and relevant electronics industry, the use of digital appliances such as a mobile phone, a digital camera and a notebook computer becomes more and more common, and develops toward the direction of convenience, multi-function and good design, in order to provide users with more choices. As users' demand for digital products gradually increases, a display panel that plays an important role in digital products also becomes the focal point of designers' attention, wherein a liquid crystal display panel has become the mainstream of display panels.

Among current liquid crystal display panels, the vertical alignment (VA) mode liquid crystal display panel has a problem of color washout when viewed in a large viewing angle. FIG. 1 is a top-view schematic diagram of a portion of a conventional pixel array substrate. Referring to FIG. 1, to solve the problem of color washout in the liquid crystal display panel, each pixel 100 on a pixel array substrate 50 of the liquid crystal display panel may be divided into two portions, namely a primary pixel 110 and a secondary pixel 120, making the primary pixel 110 and the secondary pixel 120 have different voltages. When the primary pixel 110 and the secondary pixel 120 have different voltages, liquid crystal molecules within the same pixel 100 may have more arrangement directions, and then the problem of color washout that occurs in the liquid crystal display panel in the large viewing angle may be improved.

However, in order to make the liquid crystal display panel have the above effect in a driving method of a reverse scan, a scan line 140 has to be added into the same pixel 100. But the addition of the scan line 140 reduces the aperture ratio of each pixel 100 and leads to a lowered transmittance. Besides, in order to control signals transmitted to an original scan line 130 and the newly added scan line 140 respectively, the number of driver chips has to increase to a double of the original number, leading to an increased cost of products. Therefore, how to attend simultaneously to an ideal aperture ratio of the pixels, a lower overall cost and a solution to the problem of color washout of the liquid crystal display panel is an issue worth exploring in the design of the liquid crystal display panel.

DETAILED DESCRIPTION OF DISCLOSED EMBODIMENTS

Several exemplary embodiments accompanied with drawings are described in detail below to further describe the invention in detail.

FIG. 2 is a cross-sectional schematic diagram of a portion of a display panel according to an embodiment of the invention. Referring to FIG. 2, a display panel 200 includes a first substrate 210, a display medium 220, and a pixel array substrate 230. The display medium 220 is configured between the first substrate 210 and the pixel array substrate 230.

FIG. 3 is a top-view schematic diagram of a portion of the pixel array substrate in FIG. 2, and FIG. 4 is an equivalent circuit diagram of the pixel array substrate in FIG. 3. Referring to both FIGS. 3 and 4, the pixel array substrate 230 includes a first pixel electrode 231, a second pixel electrode 232, a third pixel electrode 233, a fourth pixel electrode 234, a data line DL, a first scan line SL1, a second scan line SL2 and a third scan line SL3. In the embodiment, the display panel 200 includes a plurality of first pixel electrodes 231, a plurality of second pixel electrodes 232, a plurality of third pixel electrodes 233, a plurality of fourth pixel electrodes 234, a plurality of data lines DL, a plurality of first scan lines SL1, a plurality of second scan lines SL2 and a plurality of third scan lines SL3, for example. Since FIGS. 3 and 4 merely illustrate a portion of the pixel array substrate 230, merely one of the plurality of third scan lines SL3 are schematically illustrated.

Besides, the pixel array substrate 230 includes a first transistor 235, a second transistor 236, a third transistor 237, a fourth transistor 238 and a plurality of fifth transistors 239 a and 239 b. In the embodiment, the example is provided with a plurality of first transistors 235, a plurality of second transistors 236, a plurality of third transistors 237, and a plurality of fourth transistors 238, and therefore FIGS. 3 and 4 illustrate the plurality of first transistors 235, the plurality of second transistors 236, the plurality of third transistors 237, and the plurality of fourth transistors 238.

In the embodiment, the transistors may be Thin Film Transistors (TFTs), in order to serve as a switching element of each pixel unit in the pixel array substrate 230. Each of the transistors, in coordination with the corresponding data line DL, the corresponding first scan line SL1, the corresponding second scan line SL2 and the corresponding third scan line SL3, may select a specific pixel electrode, and display a corresponding display data by means of providing an adequate operating voltage.

In the embodiment, each of the plurality of first transistors 235 electrically connects to one corresponding first pixel electrode 231, each of the plurality of second transistors 236 electrically connects to one corresponding second pixel electrode 232, each of the plurality of third transistors 237 electrically connects to one corresponding third pixel electrode 233, and each of the plurality of fourth transistors 238 electrically connects to one corresponding fourth pixel electrode 234. Each of the plurality of data lines DL electrically connects to each corresponding first transistor 235, second transistor 236, third transistor 237 and fourth transistor 238.

Besides, the first scan line SL1 electrically connects to the first transistor 235 and the third transistor 237, and the second scan line SL2 electrically connects to the second transistor 236 and the fourth transistor 238. Each of the plurality of third scan lines SL3 is located between the corresponding first scan line SL1 and the corresponding second scan line SL2, and the third scan line SL3 electrically connects to each corresponding third pixel electrode 233 via the fifth transistor 239 a, or to each corresponding fourth pixel electrode 234 via the fifth transistor 239 b.

In the embodiment, the third scan line SL3 is used in receiving control signals for controlling each of the plurality of fifth transistors 239 a and 239 b, and the fifth transistors 239 a and 239 b further electrically connect to the corresponding third pixel electrode 233 and fourth pixel electrode 234. Thereby, the third pixel electrode 233 and the fourth pixel electrode 234 substantively adopt a design of sharing the third scan line SL3, and the design of sharing makes the display panel obtain a favorable aperture ratio.

In the embodiment, the third pixel electrode 233 is located between the first scan line SL1 and the third scan line SL3 electrically connected to the third pixel electrode 233. The first pixel electrode 231 and the third pixel electrode 233 electrically connected to the first scan line SL1 are located on the same side of the first scan line SL1. The fourth pixel electrode 234 is located between the second scan line SL2 and the third scan line SL3 electrically connected to the fourth pixel electrode 234. The second pixel electrode 232 and the fourth pixel electrode 234 electrically connected to the second scan line SL2 are located on the same side of the second scan line SL2. From another aspect, the third pixel electrode 233 and the fourth pixel electrode 234 electrically connected to the third scan line SL3 are located on the two sides of the third scan line SL3 respectively.

The pixel array substrate 230 in the embodiment further includes a plurality of capacitors C1 and C2. The fifth transistor 239 a electrically connects between the corresponding capacitor C1 and the corresponding third pixel electrode 233. The fifth transistor 239 b electrically connects between the corresponding capacitor C2 and the corresponding fourth pixel electrode 234.

In the embodiment, each first pixel electrode 231 and each third pixel electrode 233 are substantively located within one pixel, and each fourth pixel electrode 234 and each second pixel electrode 232 are substantively located in another identical pixel. In other words, a design of a pixel structure in the embodiment is to divide one pixel into two portions, that is a primary pixel and a secondary pixel. Scan signals are received in coordination with the data line DL and the third scan line SL3 to control the fifth transistors 239 a and 239 b, and the third pixel electrode 233 and the fourth pixel electrode 234 correspondingly connected to the fifth transistors 239 a and 239 b are controlled by means of the fifth transistors 239 a and 239 b. The primary pixel corresponds to the first pixel electrode 231 and the second pixel electrode 232, and the secondary pixel corresponds to the third pixel electrode 233 and the fourth pixel electrode 234.

Accordingly, the fifth transistor 239 a electrically connects between the corresponding capacitor C1 and the corresponding third pixel electrode 233, and the fifth transistor 239 b electrically connects between the corresponding capacitor C2 and the corresponding fourth pixel electrode 234. Thereby, when the third scan line SL3 receives a scan signal, voltages of the third pixel electrode 233 and the fourth pixel electrode 234 corresponding to the capacitors C1 and C2 may be changed by means of operation of the capacitors C1 and C2. When the voltages of the third pixel electrode 233 and the fourth pixel electrode 234 change, a gray scale value within the same pixel differs slightly, in order to improve on the problem of color washout of the display panel 200 in a large viewing angle.

Besides, both the fifth transistors 239 a and 239 b that may serve as control switches of the third pixel electrode 233 and the fourth pixel electrode 234 electrically connect to the third scan line SL3. Compared with the conventional technology of disposing a data line in each pixel, the design of the pixel array substrate 230 in the embodiment makes each third pixel electrode 233 and each fourth pixel electrode 234 share the corresponding third scan line SL3. That means, in the embodiment, the sub-pixel electrodes in every two pixels share a scan line. Compared with the conventional technology of disposing the data line in each pixel, the embodiment obtains a favorable aperture ratio while improving on the problem of color washout of the display panel 200 in the large viewing angle. Besides, sharing the third scan line SL3 reduces the number of driver chips controlling the scan lines, and thereby has the benefit of cost saving.

Referring to FIG. 2 again, in the embodiment, the display medium 220 of the display panel 200 may be a liquid crystal, and therefore the display panel 200 in the embodiment is substantively a liquid crystal display panel. Besides, the first substrate 210 may be a color filter substrate. The color filter substrate may include color filter films of various colors. When light passes through red, green and blue filter films in the color filter substrate, a red light, a green light and a blue light are displayed respectively, and accordingly the display panel 200 achieves the effect of color display.

The configuration of each element and relevant functions thereof in the display panel 200 in the embodiment are introduced in the above, and a driving method for driving the display panel 200 is introduced in the following. FIG. 5 is a time sequential waveform diagram of an equivalent circuit of the pixel array substrate in FIG. 4. Referring to both FIGS. 4 and 5, the driving method includes the following steps. Firstly, a first scan signal S1 is provided to a No. i first scan line SL1 to turn on a plurality of first transistors 235 and a plurality of third transistors 237 electrically connected to the No. i first scan line SL1 in a first period t1 within a frame period of the display panel 200. A plurality of first display data are correspondingly written into a plurality of first pixel electrodes 231 electrically connected to the plurality of first transistors 235 electrically connected to the No. i first scan line SL1 and a plurality of third pixel electrodes 233 electrically connected to the plurality of third transistors 237 electrically connected to the No. i first scan line SL1 via a plurality of data lines DL, and the i is an integer equal to or larger than 1.

Then, a second scan signal S2 is provided to a No. i second scan line SL2 to turn on a plurality of second transistors 236 and a plurality of fourth transistors 238 electrically connected to the No. i second scan line SL2, and a plurality of second display data are correspondingly written into a plurality of second pixel electrodes 232 electrically connected to the plurality of second transistors 236 electrically connected the No. i second scan line SL2 and a plurality of fourth pixel electrodes 234 electrically connected to the plurality of fourth transistors 238 electrically connected the No. i second scan line SL2 via the plurality of data lines DL in a second period t2 within the frame period.

Next, a third scan signal S3 is provided to a No. i third scan line SL3 to turn on a plurality of fifth transistors 239 a and 239 b electrically connected to the No. i third scan line SL3 in a third period t3 within the frame period. Meanwhile, the plurality of first display data written into the plurality of third pixel electrodes 233 electrically connected to the fifth transistors 239 a electrically connected to the No. i first scan line SL1 and the plurality of second display data written into the plurality of fourth pixel electrodes 234 electrically connected to the fifth transistors 239 b electrically connected to the No. i second scan line SL2 are influenced. Synchronously, a fourth scan signal S4 is provided to a No. i+1 first scan line SL12 to turn on a plurality of first transistors 235 and a plurality of third transistors 237 electrically connected to the No. i+1 first scan line SL12, and a plurality of third display data are correspondingly written into the first pixel electrodes 231 electrically connected to the first transistors 235 electrically connected to the No. i+1 first scan line SL12 and the third pixel electrodes 233 electrically connected to the third transistors 237 electrically connected to the No. i+1 first scan line SL12 via the plurality of data lines DL.

Afterwards, a fifth scan signal S5 is provided to a No. i+1 second scan line SL22 (not shown in FIG. 4 and schematically demonstrated in FIG. 5) to turn on a plurality of second transistors 236 and a plurality of fourth transistors 238 electrically connected to the No. i+1 second scan line SL22, and a plurality of fourth display data are correspondingly written into a second pixel electrode 232 electrically connected to the second transistor 236 electrically connected to the No. i+1 second scan line SL22 and a fourth pixel electrode 234 electrically connected to the No. i+1 second scan line SL22 (not shown in FIG. 4) connected to the fourth transistor 238 correspondingly electrically connected to the No. i+1 second scan line SL22 via the plurality of data lines DL in a fourth period t4 within the frame period.

More specifically, in the embodiment, since the fifth transistor 239 a connects between the third pixel electrode 233 and a corresponding capacitor C1, and the fifth transistor 239 b connects between the fourth pixel electrode 234 and a corresponding capacitor C2, the fifth transistors 239 a and 239 b control the corresponding capacitors C1 and C2 respectively to influence voltages of the corresponding third pixel electrode 233 and fourth pixel electrode 234 when the third scan line SL3 receives the third scan signal S3 in the third period t3 within the frame period.

More concretely, the first pixel electrode 231 and the third pixel electrode 233 are located in the same pixel, and the second pixel electrode 232 and the fourth pixel electrode 234 are located in the same pixel. Thereby, when the voltages of the third pixel electrode 233 and the fourth pixel electrode 234 change, there is a voltage difference between the first pixel electrode 231 and the third pixel electrode 233; on the other hand, there is also a voltage difference between the fourth pixel electrode 234 and the second pixel electrode 232. If there is the voltage difference between the first pixel electrode 231 and the third pixel electrode 233 within the same pixel, the gray scale values thereof are different, and the problem that the colors in the display panel 200 appear lighter in a large viewing angle is improved. Similarly, the same effect is achieved if there is the voltage difference between the second pixel electrode 232 and the fourth pixel electrode 234.

Besides, in the third period t3 within the frame period, the fifth transistors 239 a and 239 b controlling and making each of the pixel electrodes within the same pixel have the voltage difference electrically connect to the third scan line SL3. Thereby, at the mean time that the third scan line SL3 receives the third scan signal S3 and makes the voltage difference between each of the pixel electrodes within the same pixel change, a fourth scan signal S4 may be synchronously provided to the No. i+1 first scan line SL12 to turn on the plurality of first transistors 235 and the plurality of third transistors 237 electrically connected to the No. i+1 first scan line SL12, and the plurality of third display data may be correspondingly written into the plurality of first pixel electrodes 231 electrically connected to the plurality of first transistors 235 electrically connected to the No. i+1 first scan line SL12 and the plurality of third pixel electrodes 233 electrically connected to the plurality of third transistors 237 electrically connected to the No. i+1 first scan line SL12 via the plurality of data lines DL. Besides, although the driving method applies to a circumstance of a forward scan in the display panel 200, the driving method in the embodiment is similarly suitable when a circumstance of a reverse scan is adopted in the display panel 200. The steps of the reverse scan are similar to those of the forward scan, and therefore the steps are not elaborated here.

Based on the above, the display panel of the invention includes a plurality of third scan lines shared by pixel electrodes within different pixels, and the shared scan lines are used to increase the aperture ratio of the display panel. Besides, the plurality of fifth transistors electrically connected to the third scan lines may serve as the control switches controlling whether the scan signals enter each of the pixel electrodes connected to the third scan lines. In coordination with the capacitors electrically connected to each of the fifth transistors, the voltage of each of the pixel electrodes connected to the third scan lines may be changed, in order to improve on the problem of color washout of the display panel in the large viewing angle. In addition, in the driving method for driving the display panel provided in the invention, the third scan signal may be provided to the No. i third scan line and the fourth scan signal may be provided to the No. i+1 first scan line simultaneously within one particular display period in the frame period, in order to solve the problem of color washout of the display panel. The driving method is suitable for the circumstances of both the forward scan and the reverse scan in the display panel.
